A 250-kg crate is on a rough ramp, inclined at 30° above the horizontal. The coefficient of kinetic friction between the crate and ramp is 0.22. A horizontal force of 5000 N is applied to the crate, pushing it up the ramp. What is the acceleration of the crate? A) 8.4 m/s² B) 10 m/s² C) 12 m/s² D) 13 m/s² E) 3.4 m/s²

To find the acceleration, calculate the net force acting on the crate. The horizontal force has a component along the ramp, and friction and gravity oppose the motion. Use the formula: net force = applied force component - friction force - gravitational force component. Then, use F = ma to find acceleration. The correct calculation gives approximately 8.4 m/s².
